• Visual Studio 2008 (Pre-release) Overide default Namespace for a datacontract

  Hi, I am using the IRequestChannel to send and receive messages to/from a WCF webservice. My problem is that when I create a message and send it using the IRequestChannel.Request method the namespace that is used to serialize/deserialize the message body object is http://schemas.datacontract.org/2004/07/Clr.Namespace whereas the namespace used by the server is of a different format. I tried using the ContractNamespaceAttribute to overide the default namespace of my assembly but that didnt work (Since IRequestChannel is not defined in my assembly). Is there some way for me to get around this namespace problem Firdosh You can define the body of your message as a [DataContract] class, and use t ...Show All

• Visual C++ Ambiguity of Common Interface in two COM component when generating RCW by VS2005

  My situation is described as below: 1. Define an interface in "CommonInterface.idl": interface Interface1 : IUnknown { [, helpstring("method Add")] HRESULT Add([in] int a1, [in] int a2, [out] int *sum); }; Compile it to generate corresponding .h, _i.c, _i.p files; (I do not know how to compile a sole .idl file, so I create a ATL project, write the definition of interface in .idl flieand compile it) 2.

• Visual Studio Tools for Office Cypress Outlook 2007 addin installation problems

  I have some addins for Outlook 2007 developed using Cypress and both VB.NET and C#. If I run the addins from the VS 2005 IDE they run with no problems. If I compile as release mode they run from the IDE, start Outlook and run with no problems. However, if I install after compiling the setup project and try to run the addin by just starting Outlook (on the same dev machine) the addins won't run and the error is the ever helpful: "Not loaded. A runtime error occurred during the loading of the COM Add-in" In cases like this do I need to follow the deployment steps outlined in http://msdn.microsoft.com/office/default.aspx pull=/library/en-us/odc_vsto2005_ta/html/officevstowindowsinstallerwalkthrough.asp Or sho ...Show All

• Visual C# Passing a reference to a value type from c# to c++

  I am calling a native C method from a C++/CLR DLL. This method takes a float* as an output parameter.

• SQL Server Good design?

  Hi! I want to add "inheritance" to my database. I have of table X witch attributes a1, a2, a3, a4, a5, a6 and second table Y with attributes a1, a2, a3, a7. I want to create additional table Z with attributes 1a, a2, a3, key and tables X: key, a4, a5, a6 and table Y: key, a7. I have more of those sub-class. Set of common attributes is about 5-10. Additional attributes range from 1 to 20 per table. We have also large dynamics of our database. Often (1 per month) we have to add about 2-5 attributes to some subclass (or remove some attributes). It's good idea for "attributes inheritance" I know those disadvantages: to insert (update, delete) record from X, I have to insert record to Z and X I fou ...Show All

• SQL Server How do I create a Integration Services project programatically???

  hi everyone, My vb .net app creates programatically a package. I mean, you can provide name, description, number of OLEDB/ADO connections, variables and so on, where it's stored, from a WinForm. Up to the moment, process only creates boxes separately wihtout links. My concern is after this successful cycle I only can open that DTSX and see its components but executing button is disabled (only possible with DTEXECUI.exe) from BIDS. Only when I create a project (DTSPROJ) and then I put that same .DTSX inside I am be able to execute it. Well, up to here all of this is very good. Things were created this way for some reason. My question now is how do I from my application in order to create dt ...Show All

• Visual C# Using Calendar.SelectedDate to update Gridview

  Hi, I'm fairly new to C# and Visual Studio, so any help is much appreciated. I am attempting to create a webpage with two webzones, one containing a Calendar object and the other containing a Gridview which is (currently) linked to an Access database. I have a "Created" date field in the Gridview and I would like to filter the Gridview to show only rows in which the "Created" date equals the Calendar.SelectedDate. I've added the SQLDataSource to the page and configured the Data Source in many different ways with no success. The SELECT statement that I thought should have worked is: SELECT Created, Event, Personnel_Contacted, Remedy_Num, Created_By FROM tblOpsLog WHERE Created = wpCalendar.SelectedDate (th ...Show All

• Windows Live Developer Forums class=VE_PlaceList_Title

  Could someone please tell me what this is and why it has reared it's ugly head on the map when calling map.GetRoute(start, end, null , null , onGotRoute); Sorry about the confusion in the thread. Your post was helpful. What I ended up doing was locating the DIV id and then setting that div element to display:none. There is another child DIV element inside that DIV which holds an A element which is loaded with an onclick event that holds the coordinates that need to be fired to complete the driving directions. What I want to do is fire the onclick event automatically without the user having to click on the link. That should take care of the problem.   Thanks ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Best Way to Ensure 30 fps Frame Rate

  Hi. I wrote this in another thread I just started : I am trying to play RGB video at 30 fps, so I set the Direct3D device's FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT (which is 60 for most monitors) and set PresentationInterval = D3DPRESENT_INTERVAL_TWO. When reading this, I just realized that if the monitor's frame rate is not 60, then my application will not output the video at 30 fps. How do I ensure the 30 fps frame rate Thanks, Celios Celios, I assume you mean you are concerned that users have monitors with other refresh rates. That is a valid concern. I assume you would be worried about monitors that have refresh rates set > 60 Hz (as there are not too many that would fall bel ...Show All

• Audio and Video Development Problems with XBOX 360 HD DVD Player

  I continue to run into issues with the xbox 360 hd dvd player every time I insert an hd concert dvd. I do not have any issues with the hd movies but have had issues with every concert inserted. Does anyone know of a solution I've selected Dolby digital. Think I might try a different USB cable... It seems to me that there is a signal loss between the HD DVD and the console. (I know this is isn't a support forum, but was hoping there could be a software "tweak" to fix it.) Thanks. ...Show All
